dependency-injection

What problem does it solve?

Dependency injection reduces hidden coupling by requiring explicit dependencies at construction and ensuring a clear configuration flow from entry points to services.

Core Features & Use Cases

• Explicit constructor-based dependencies to avoid hidden defaults.
• Fail-fast configuration: invalid/missing dependencies raise immediately.
• Clear separation of concerns between wiring/initialization and business logic.
• Testability: easy to supply mocks for unit tests.

Quick Start

Create a service with required collaborators and wire them in the application entry point. For example, instantiate Repository and MetadataService and pass them to the service constructor in the composition root.
